Kensington Palace was one of Queen Anne's main residences, and it currently has a display of costumes made by Sandy Powell for the film The Favourite which I saw recently and hugely enjoyed.
Going clockwise from left to right, you can see Harley's wig and jacket, the Queen's robes, Abigail's maid outfit, which is made from denim, Abigail's black dress, which was made from African material purchased from Brixton market, and Sarah Churchill's blood stained hunting jacket and trousers.
